Anti-government demonstrators in Egypt have clashed with police as they marked the second anniversary of the uprising that toppled Hosni Mubarak.

The protesters are demanding greater political and economic change, and accuse both President Mohammed Morsi and the Muslim Brotherhood, the Islamist movement to which he belongs, of betraying the promises of the revolution.

BBC Arabic's Marwa Nasser met some of them on the streets of Cairo.

The revolution would have been something good if we could have changed the country.

We got rid of Mubarak only to give the country to an Islamist who used to be in jail.

You can't just give the country to someone who was in prison.

Those who started the revolution are youths, but none of their demands were achieved. I'm concerned about the results of today's new revolution, because Islamists are taking over the country.

I don't feel any difference between Mubarak and Morsi.

The president doesn't care about Egyptians; he cares only about his family and clan.

Layla Adel Shehata, 17, student

We demanded "bread, freedom and social justice", and none of that has been achieved.

Everything is the same - unemployment, bad education. The poor don't even have bread anymore.

We called for human dignity. Where is that dignity when they are once again beating and killing us?

They forged the results of the elections and the constitutional referendum.

We can't allow a group of Muslim Brotherhood leaders, sent by the United Sates, to rule Egypt.

We refuse one party to rule Egypt. They have failed to change anything.

Maha Mohammed, 36, business owner

I spent the 18 days of the revolution in Tahrir Square.

This revolution is for our children. The new generation needs to see change.

Prices have increased even more, and we're back to square one.

We have toppled a gang of thieves only to bring in a new gang of thieves instead.

The ruling party is the same as [Hosni Mubarak's former ruling] National Democratic Party, but with beards.

Mohammed Farid, 31, graphic designer

I don't believe in reform. You destroy a regime to build a complete new one.

This is not a revolution, they are fooling us. Nothing has changed since 25 January 2011.

None of our demands have been met. Every day that passes we move three years back in time. Nothing has been changed.

Ask anyone who takes public transport - it's all the same. People are going crazy; they talk to themselves in the street.

The revolution has failed. Nobody can make a living anymore.

I can understand that prices of food and petrol would increase for just a few days after the revolution, but it continues to increase and it's not going to stop.

Momdouh Mohammed Hussein, 51, worker

I came from Aswan to take part in the protests today in Tahrir Square. Nothing has changed for us, the residents of Nuba.

We've been suffering for more than 30 years now and we thought things would change after the revolution.

We are not represented in the constitution, and we weren't represented in elections.

We met the president and members of the Muslim Brotherhood. They promised to give us our land back, but they haven't kept their word.

We provide security for this country in the south. We shouldn't be neglected in such way.

Mona Mohammed, 45, housewife

Until now nothing good has happened. We feel things are getting worse. Nothing has changed.

The revolution sought to improve life for poor and middle class families, but it hasn't brought them anything. The poor are getting poorer.

I have never travelled to Tahrir Square before. This is the first time I have joined any protest. I'm here for change, not for celebration.

I want to see this country move forward and the factories resume work. I want to see an end to unemployment and to thuggery. This country must change.

Ibrahim Abdul Kader, 54, accountant

There's no doubt that this country needed a revolution. But it took a different turn. We thought a solid plan would emerge after the revolution. Until now nothing has changed.

We were hopeful when Morsi took over. I thought he would put a full plan in place so that the country could progress under any future governments. We didn't see any planning or renaissance like they told us there would be.

The rate of poverty in Egypt is way too high. Some people are homeless and others can't afford their medicine. We wish we could feel some luxury.

Maher Abdul Rasoul, 28, lecturer

Two years ago, the demands of the revolution were "bread, freedom and social justice"; and two years later our demands are still the same. Nothing has changed. The poor can't find bread now. The government have exhausted them with new taxes.

The only demand that was partly achieved is freedom. We were successful in snatching some of our freedom with our own hands. The new regime didn't secure that freedom for us. We completely overcame our fears.

As for social justice, we only replaced one gang by another. There's still no minimum wage or maximum wage. The private sector is still in control and all the laws are only drafted on paper.

Farahat Mohsen, 22, painter

The only thing that changed after two years of the revolution is that our president has a beard. The regime hasn't changed.

We changed after the revolution and became united. The young people of the revolution know each other and feel for each other. We know when we will go to Tahrir Square and when we will start a sit-in.

We're not here today to just gather in the square - it's a new revolution. We will not leave this time until we witness a real change.
